Photosensitive body for electrophotographical use and manufacturing method thereof

Abstract

A photosensitive body for electrophotographical use has a conductive base body and a marking area provided thereon. The maximum surface roughness of a photosensitive layer provided right on the marking area is specified not to exceed 2.5 μm. And also, a ratio of the optical reflective index of the marking area to the optical reflective index of the non-marking area is specified to be in a range of 0.3 to 0.7. In this manner, even when the photosensitive layer is thin (not exceeding 25 μm), it is possible to prevent problems such as inadequate cleaning and toner falling. Hence, it is possible to offer a photosensitive body for electrophotographical use which can constantly produce high quality copied images.

What is claimed is:  
     
       1. A photosensitive body for electrophotographical use, comprising: 
       a conductive base body having a first surface part and a second surface part, the second surface part having optical reflective characteristics different from those of the first surface part; and  
       a photosensitive layer provided on the conductive base body by applying a photosensitive liquid,  
       wherein the second surface part is formed so as to have a portion on which the photosensitive body flows more easily in providing the photosensitive layer than on the rest of the second surface part.  
     
     
       2. The photosensitive body for electrophotographical use as defined in claim  1 , 
       wherein the second surface part has processed parts and unprocessed parts pointing in a direction not orthogonal to a gravity direction of the conductive base body upon the application of the photosensitive liquid and being separated mutually by intervals, the unprocessed parts continuously extending in a direction not orthogonal to the gravity direction of the conductive base upon the application of the photosensitive liquid.  
     
     
       3. The photosensitive body for electrophotographic use as defined in claim  1 , 
       wherein the second surface part has a groove part for collecting and allowing an excessive amount of the photosensitive liquid to flow down in the second surface part.
